Hi  Alan..
I'm not an authority however I purchased the same brand(2 yrs ago) from
"Dick Smith"  a different Model , but packaged with BitCom Software.
While I use that Windows Package(successfully) I also have had no
problem using Telix(Dos) with HAYES Generic.

The Handbook refers to"QUANTUM DATA SYSTEMS LTD"
I also have an Operation addendum for 144UF+; 144UB; and 144UB
     Auto Reliable Mode  AT&F&W
     MNP                  AT&F1&W
     Direct Mode         AT&F2&W
 Hope this is of some help
